FIR数字滤波器在工程上运用广泛．窗函数法设计FIR数字滤波器是典型的设计方法。目前。相关课程的教科书对窗函数法设计FIR 散字滤波器这部分内容讲解不够细致，学生掌握感到有难度。本文针对窗函数法设计FIR数字滤波器的相关问题．即数字滤波器与模拟样本 滤波器的关系、截断点如何取值和数字滤波器的线性相移特性，结合实例进行分析。并借助Matlab仿真软件对设计进行了分析和验证．(FIR digital filters widely used in engineering. Window method is a typical design FIR digital filter design methods. Present. Related courses textbooks window functions designed FIR filter scattered words to explain this part carefully enough, students are difficult to master. This window function method for the design of FIR digital filters related issues. Samples of the digital filter and analog filter between values and the cut-off points to the linear phase shift digital filter characteristics, with examples for analysis. And using Matlab simulation software design analysis and verification.)

生成一个一定参数的原信号，并附加一个符合均匀分布的随机噪声，分别画出该信号经过均匀采样的频谱图以及经过非均匀采样的频谱和时域图(Generate a certain parameter of the original signal, and attach a line with uniformly distributed random noise were drawn through uniform sampling of the signal spectrum as well as through non-uniform sampling of the spectrum and time domain)

对声波方程的数值模拟，并加上了PML边界条件，研究波场在是否加边界的差异；此程序简单易懂，适用于初学者(Numerical simulation of acoustic wave equation, plus the PML boundary condition, wave field research plus the difference in whether or not the border this program easy to understand for beginners)

MATLAB 在光学教学中的应用,有示例,模拟光的双缝干涉％单缝衍射和光栅衍射.(MATLAB Teaching in optical applications, there are examples of simulation of light double-slit interference single-slit diffraction and diffraction gratings.)

计算循环平稳信号的4累积量的算法，希望对大家有所帮助(Cyclostationary signals calculated cumulant algorithm 4, and they hope to help everyone)

说明：  非正弦信号的波束形成程序，和利用相位的常规波束形成不同，非正弦信号的波束形成首先匹配滤波，提取包络，然后延时相加，(Non-sinusoidal signal beamforming process, and the use of conventional beam-forming phase is different from non-sinusoidal signals in the first match beamforming filtering, envelope extraction, and then add delay,)

通过这种方法，可以实现matlab对于ansys的调用。 附件中为matlab程序和ansys命令流。( In this way, you can call the matlab for ansys. Annex matlab program and ansys command stream.)

这为一个相控阵列天线的波束形成与指向控制的ＭＡＴＬＡＢ仿真软件(This is a phased array antenna beam forming and pointing control of the MATLAB simulation software)
